Original application filed September 15, 1910, Serial No. 582,214. Divided and'this applicationfflled May 7, 1913; serial No. 766,145.

To (ill whom it mag concern tain new and usefullmprovements in"Type- \Vriting .Machines,-of which the following is a full, clear, and exact description.

This invention relates more particularly"- to carriages for foldable visible typewrit ng, 'machine's,kand'- is a division of my application- N0. 582,21-1, filed Sept. 15, 1910,

now Patent.-

1,060,027, dated May "20,

One of the principal objects of the-invenso formedasto permitthe same to be properly held in position and adapted for use in connection with ball-bearings.

Anotherobject of the-invention is to pro- I vide 'a platen carriage having apart thereof serving tozassist' in the operation of the linespacing mechanism.

. I A further ob'ect of the inventioriis to provide simple and eflicientintegral means forming a part of the carriage and bed whereby a ball-bearing may be interposed between the base of the carriage and the lengthwise of said bed,

A still further ob ect With these and otherob'ects in view, the

'-.-shif-t "mechanism in :order that the type- ,invention will be hereinafter, more particuis made to provide means-forminga part of the line-spacing mecharnsm;

Vvhlle I show the invention as partlcu- .bed to adapt the carriage to run easily of the invention suitable construction.

The bed'16 along which the carriage is.

larly applicable to -a typewriter-in which the plate'n' carriage -is foldable or movable into compact relation to another part of the j suchmachinesthitt they be made light and strong,- it will be understood that the inven .tion is applicable to typewriting machines of variousconstructions.

- .The frame l0f'may be 'made of sheet steel to a" part of which the hangers 11 are secured. A type-bar 1'2 is 'pivota'llyheld to each hanger 11 and this-type-bar is oper ated by the usual. key-leversyand carries-atype-l1ea'd--13,.the said type-head being adapted to lie-moved againstthe work-,"sheet held to thefplaten' 14. The platen '14 is held to rotate in a carriage 15,*thelatter being formed of a single'piecelof sheet steel or other metal. and adapted to move along a carriage bed 16. The carriagebed 16 is held by screws 17v oryotherwise to arms 0r bars 1 18 forming apart of a foldable support 19.

This support 19 has bars- 20 on opposite sides of the machine and these bars 20 are pivoted, at 21, to "the bars 18 to adapt the carriage to be folded forward into substantially overhanging relation to the keyboard;

Each bar .20 is 'heldto'a post or slide 22.

These slides are guided lilniheir vertical movement by thimbles orbt ackets 23 located at the rear .corners'of the machine frame to adapt the support and carriagetolbe moved vertically by means of any suitable platen hea'dsj may have; a plurality of characters thereon. The construction of the machine frame, the p foldabl'e' 'sup'port and the parts arrangedin the machine frame'form no part ofthe present invention and may be of, any

adapted to travel vfor letter spacing may be made of sheet steel or other metal which.

is pressed vor formed in such-a way as to make the same very light and strong and also serves as a guide forythe car riage 15. This bed 16 has an upwardly turned 'flange 24 at one edge, and a flange 25 extendinglengthwise of said bed along the other edge, and. said flange isflprovided'with a rib 26 near the bot-tom thereof which isformed by depressing said flange, and along the base of'the bed are longitudinally extending ribs 27, 28 and 21: These ribs form' longitudinally extending channels, raceways or guideways 30 and 31 in which are balls 32. --There are three balls shown, two arranged in the guideway 30 and one in the guideway 31 and these balls are connected by a wire 32- so that all of said balls inove in unison, though other means than the special form of'ball-bearing may be'provided.

Above the bedlfi is the base 33 of the carriage 15. This base is provided with an upwardly extending flange 34 at one edge, and a flange 35 .at' its other edge, and said flange 35 is held against independent lifting movement by an angular bracket 36 secured to thewall or flange 25 of the carriage b'ed', while the upper edge of the flange 34 is vengaged by a screw or other device 37 whereby the carriage may move along the bed transversely of the machine in such a 'Way as tobe shifted with the bed 16. The

carriage base 33 with its flanges 34 and 35 is located within the flanges. 24 and 25 of the carriage bed and rests upon the balls 32 and is provided with a channel or guideway 38' extending lengthwise thereof and opposed to' the guideway 30 of the bed 16.' I

This guideway 3S is formed by depressing the base 33 of the carriage, as at 39, to form two ribs which are opposedto the ribs 28 and 29 of the bed 16 and which assists in properly guiding and holding the balls in place.

The carriage has integral end walls 40 and '41. which may be joined together by a transversely extending rod 42 at the rear thereof and one of said ends, as 40, has two outwardly extending integral arms 43, and an integral finger portion 44 which extends upwardly to provide a fixed gripping part andwhich forms a part of the line-spacing mechanism. This finger portion cooperates with the pawl-carrying pivoted lever 45, shown in Fig. 2, and as the finger portion 44 is fixed with respect to the. lever 45, the

finger portion and lever 45 may be grasped by the hand and the former more readily operated than if the finger portion were dispensed with. The arms 43 have openings 46 formed by dies, or otherwise, and in said openings is held a rod 47 which serves as a pivot for the lever 45.

By forming the carriage in the manner shown, it will be evident that the said carriage with its-finger portion 44 and the arms 43 serving as a support for the line-spacing lever may be made of a single piece of sheet metal in such a way as to be very light and dispenses with the necessity of forming the frame of a plurality of parts, thus materially reducing the cost of manufacturing the same. It will be further evident that the carriage bed may be made of a single piece of metal and is so formed as to be very strong and light; that simple' means is pro vided whereby ball-bearing raceways may be provided for the carriage; that simple and efficient supporting and guiding means is provided for the carriage; and that said parts may be readily made and assembled.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
